I am creating a docker container that will host a web app. The container is an ubuntu18.04 vm with a flask app + gunicorn running. I am trying to configure ssh but something wonky is going on.
In my docker file I do something along the lines of:
RUN useradd -s /bin/bash -m username
This works fine and the user gets added. I have a separate process that run-in the background and adds to the /home/username/.ssh/authorized_keys to allow for password less ssh. Again this works, the weirdness comes in when the actual ssh happens.
When I ssh in I see that $HOME is set to /root instead of /home/username. If I try to cd ~/ it gets an access denied because it is trying to go to /root. Why is HOME incorrect but I am connected as the correct user?
Note: in the below output I changed the username as it is a bit identifying
Output:

The user in passwd file:

This is confusing the heck out of me. Any help would be appreciated.
